Camera Research

For the best results the ReacTIVision website says;

"You should make sure that the camera has an acceptable lens and sensor size. For lowest latency and best performance we recommend firewire cameras from the top range, such as industrial cameras with a high framerate, resolution and sensor size. These cameras usually also come with high quality C-mount lenses. Cheaper firewire cameras, such as the unibrain fire-i also allow optional wide-angle lenses. From the large range of available USB cameras we recommend to use high end models with a native resolution of at least 640x480 at a frame rate of 30Hz. A very affordable and relatively good camera for this purpose is the Sony PS3eye, which is also working well under Windows, Linux and Mac OSX. DV cameras supporting full-frame mode are suitable, while those with interlaced mode only, will not work at all."

If I had a much bigger budget  for my project I would of liked to get a ATV pike or AVT guppy, my suspicions tell me that the true ReacTable works with this sort of camera.

These AVT guppy cameras are small firewire CMOS and CCD cameras, designed to perform very well. They are pretty pricey though and start from around £550 - £1000. You can find them here...

I couldn't find a quote online for the AVT Pike cameras but I assume the are similar in price to the AVT Guppy.
 
CMOS and CCD

This is taken from (http://www.dalsa.com/corp/markets/CCD_vs_CMOS.aspx)

"CCDs have traditionally provided the performance benchmarks in the photographic, scientific, and industrial applications that demand the highest image quality (as measured in quantum efficiency and noise) at the expense of system size. CMOS imagers offer more integration (more functions on the chip), lower power dissipation (at the chip level), and the possibility of smaller system size, but they have often required tradeoffs between image quality and device cost."

Things to consider.......

After researching different camera's I have come to the conclusion that I will not be able to afford a fast camera such as the AVT Guppy just yet. In the meantime I will find an alternative camera to use.
